Let Bn, 0 ≤ n ≤ ω, be the equational classes of distributive p-algebras (precise definitions are given in §1). It has been known for some time that the elementary theories Tn of Bn possess model companions ; see, e.g., [6] and [14] and the references given there. However, no axiomatizations of were given, with the exception of n = 0 (Boolean case) and n= 1 (Stonian case). While the first case belongs to the folklore of the subject (see [6], also [11]), the second case presented considerable difficulties (see Schmitt [13]). Schmitt's use of methods characteristic for Stone algebras seems to prevent a ready adaptation of his results to the cases n ≥ 2.The natural way to get a hold on is to determine the class E(Bn) of existentially complete members of Bn: Since exists, it equals the elementary theory of E(Bn). The present author succeeded [12] in solving the simpler problem of determining the classes A(Bn) of algebraically closed algebras in Bn (exact definitions of A(Bn) and E(Bn) are given in §1) for all 0 > n < ω. A(Bn) is easier to handle since it contains sufficiently many “small” algebras-viz. finite direct products of certain subdirectly irreducibles-in terms of which the members of A(Bn) may be analyzed (in contrast, all members of E(Bn) are infinite and ℵ-homogeneous). As it turns out, A(Bn) is finitely axiomatizable for all n, and comparing the theories of A(B0), A(B1) with the explicitly known theories of E(B0), E(B1)-viz. , , a reasonable conjecture for , 2 ≤ n ≤ ω, is immediate. The main part of this paper is concerned with verifying that the conditions formalized by suffice to describe the algebras in E(Bn) (necessity is easy). This verification rests on the same combinatorial techniques as used in [12] to describe the members of A(Bn).

The article presents the results of a validating study carried out within the framework of the research under the grant "Building predictive models of the dynamics of the development of mobilization-type Internet communities". The aim of the study is to test the empirical model of integration of the Internet community in terms of the validity of the content and the validity of the criteria. The subject of the study is the validity of the criteria and integration factors identified in this model. The research methods are a survey of internal experts and a comparative analysis of assessments of the criteria and factors of integration of the specified model by external and internal experts. The results obtained allow us to conclude that it is correct to identify the criteria and factors for integrating the Internet community at the first stages of the research project. Differences in the assessment by two types of experts of the significance of some criteria and factors of integration of Internet communities receive the fixation of two observation positions - external and internal - as two types of explanation, namely, an understanding and descriptive explanation, respectively. The conducted research not only allows to introduce new criteria and factors of integration into the empirical model of integration of the Internet community, but also to draw an important theoretical conclusion. Online communities in their development manifest both the properties of real social groups and the properties of networks. These two methodological attitudes can be equally successfully applied in the analysis of online communities of the mobilization type. In the first case, analyzing the behavior of the online community as a social group, the dynamics of its mobilization function is mostly recorded. In the second case, analyzing the behavior of a community as a network, the dynamics of its volume and the dynamics of information potential are described to a greater extent.

The main purpose of the presented article is to reveal the potential of social psychological knowledge for the analysis of radicalisation of young people. In the introduction, the features of socialisation in the modern world are discussed. Special attention is drawn to the role of the Internet in the socialisation of adolescents and young people. It is noted that the dominance of audiovisual information contributes to the reduction of reflexivity and promotes the so-called clip thinking, which has become an integral characteristic of adolescents and young people. It is emphasized that life in the modern society is associated with a number of changes taking place simultaneously at different levels, and uncertainty has become its important feature. Extremism and radicalisation are considered as a reaction to uncertainty, a way to overcome it. The main part of the article is devoted to the analysis of models of radicalization describes in various works. Finally, perspectives of further investigation into the subject are outlined.

The Subject

The topic of patriotic consciousness and patriotic education today claims to the status of a nationwide idea, so the research interest in this issue is unusually high. The study of patriotic consciousness should begin with an analysis of the subject which the patriotic feelings of citizens are directed on. This subject is the motherland and its image in the minds of citizens. The article gives an overview of the data, which is used for the semantic deferential method «Image of Motherland» and the procedure of studying of the image of the Motherland based on this method. The sample was 165 respondents. Based on the results obtained, it is concluded that the use of this methodology is a tool, which lets us to determine social ideas about the image of the Motherland. It has been proved that the image of the Motherland in consciousness reflects the ideas about the country and the state in which the respondents were born and raised, it is not associated with a so-called “Small homeland”, but with a certain commonality of territory, nature and culture. There is reason to believe that the image of the Motherland in the human mind can be viewed as an image “for oneself” and an image “for others”: in the first case, the Motherland is perceived as big and strong, interesting for life and comfortable, simple and cultural; Motherland “for others” is bold and friendly, strong and kind.

The Impact

In this article we focus on identifying the specificity of digital transformation within the public sector. The aim of the article is to present the main mechanisms resulting from the introduction of digital innovations that have changed the functioning of the public sector. Starting from a discussion on the technological requirements of digital transformation, we briefly characterise the use of computers and the Internet in public administration, resulting in the development of e-services and administration. The main part of the article is devoted to discussing the specificity of the implementation of the new digital technologies in public administration, focusing mainly on artificial intelligence and blockchain technologies. Our thesis is that the impact of innovative digital technologies on the operation standards and structure of public administration should be analysed through the prism of interrelated mechanisms of datafication and platformisation, characteristic for the digital economy. The adopted methodology, which is based on an analysis of the subject literature and an analysis of new technology implementations in public administration in EU countries, indicates the pilot, random and non-transformational nature of these implementations, partly due to the lack of well-established methodologies to study and assess the maturity of digital transformation within the public sector.

Attention has recently been drawn to the obscurity of the usual presentations of Mayer's method of solution of the total differential equationThis method has the practical advantage that only a single integration is required, but its theoretical discussion is usually based on the validity of some other method of solution. Mayer's method gives a result even when the equation (1) is not integrable, but this cannot of course be a solution. An examination of the conditions under which the result is actually an integral of equation (1) leads to a proof of the existence theorem for (1) which is related to Mayer's method of solution in a natural way, and which moreover appears to be novel and of value in the presentation of the subject.

The Continuum

This paper focuses on Charlotte Wood’s 2015 dystopian novel The Natural Way of Things. Set in an unnamed place in the Australian outback, it recounts the story of 10 girls in their late teens and early twenties who are kept prisoners by a mysterious corporate organisation for their sexual involvement with an array of powerful men. The novel’s title invites two main readings: the first, and perhaps more obvious, along gender lines; and the second, which will provide the backbone to my analysis, within the framework of the natural world, the animal kingdom in particular. The Natural Way of Things has been described as a study in contemporary misogyny and the workings of patriarchy. The ingrained sexism of society—the insidious, normalised violence against females, often blamed on them, glossing over male responsibility—is undoubtedly the central topic of Wood’s work. Without losing sight of gender issues, my approach to Wood’s novel is inspired by Rosi Braidotti’s posthuman theories on the continuum nature–culture and the primacy of zoe—“the non-human, vital force of life”—over bios, or life as “the prerogative of Anthropos” (Rosi Braidotti). According to Braidotti, the current challenges to anthropocentrism question the distinction between these two forms of life, highlighting instead the seamless connection between the natural world and culture and favouring a consideration of the subject as embodied, nomadic and relational. My reading of The Natural Way of Things in light of Braidotti’s insights will be supplemented by an analysis of the novel in the context of transmodernity, both a period term and a distinct way of being in the world theorised by critics such as Rosa M. Rodríguez Magda and Marc Luyckx, who emphasise the relational, interdependent nature of contemporary times from a more human-centred perspective. The Natural Way of Things is also a story of female empowerment. This is especially the case with Yolanda Kovacs and Verla Learmont, the two protagonist women, who step out of their roles as victims and stand up to their guards. My analysis of the novel will revolve around these two characters and their different reactions to confinement and degradation. I conclude that although a more zoe-centred conception of the human subject that acknowledges the human–animal continuum should definitely be welcomed, literally “becoming animal”, as Yolanda does, deprives one of meaningful human relationality, embodied in the novel in Verla’s memories of her caring, empathic relationship with her father.

The merging of knowledge management and hybrid learning has gained more and more attraction and has been put in the focus of interests lately, for the simple reason that both areas can benefit from each other. As a result, this chapter deals with knowledge management for hybrid learning. This chapter begins with a short introduction, followed by a brief clarification showing our understanding of hybrid learning. Afterwards, knowledge and associated attributes are defined precisely – definitions are derived and taxonomies for knowledge are described. This section closes with a first reflection on knowledge in the context of hybrid learning. Subsequently, the authors take a closer look at knowledge management by introducing different schools of thought and models for knowledge management. Opportunities to delve deeper into the subject individually are offered passim. The main part of the chapter provides a comprehensive view of knowledge management for hybrid learning. The described features range from general conclusions to theoretical aspects, exemplary projects, and finally practical aspects – previous deliberations are brought together, current insights concerning the research perspective are described and tools as well as techniques which foster knowledge management for hybrid learning are presented. Finally, a critical reflection as well as an outlook and some thoughts concerning future issues conclude this chapter.

Pargas in Finland and MansjSand and Tennberg in Sweden are the only three Fennoscandian contact metamorphic limestone occurrences of which systematic accounts have been published; in the first case by A. Laitakari (1) and in the two latter ones by the present author (2, 3). A more complete analytical programme would have been desirable, and unfortunately many of the analyses are incomplete, especially as regards the determination of the valency of the iron. Nevertheless, the available data, and a few I have been able to add later, may suffice to give us a general idea of the paragenetical and chemical differences between these Archaean mineral parageneses and those of much younger age which occur in connexion with the limestone masses associated with the alkaline occurrence of Alnö in Sweden.

ABSTRACTThe purpose of this paper is to give an account of some hitherto unexplained phenomena connected with the use of the Eskimo ‘relative case’. A deep structure is proposed that not only will account for the occurrence of certain surface morphemes, but also, and in a natural way, for the semantic affinities that exist between certain types of noun phrases and the transitive sentence in Eskimo. In particular, it is shown that in phrases of the type ‘the man's house’, there exists evidence for considering ‘man’ as the subject noun phrase, ‘house’ as the object noun phrase of some deep structure. The transformational machinery involved in deriving the correct surface structures is shown in some detail. A discussion of older terminology in Eskimo grammatical tradition provides additional, indirect confirmation of the naturalness of the proposed explanation.
